In mathematics, an equivalence relation is a binary relation that is reflexive, symmetric and transitive. The relation "is equal to" is the canonical example of an equivalence relation, where for any objects a, b, and c:

• a = a (reflexive property),
• if a = b then b = a (symmetric property), and
• if a = b and b = c then a = c (transitive property).
